The following situations can cause the transmission to
operate at higher temperatures:
• Towing a trailer
• Hot outside air temperatures
• Hauling a large or heavy load
• Low transmission fluid level
• High transmission fluid level
• Restricted air flow to the radiator and the auxiliary
transmission oil cooler (if equipped).
A temporary solution to hotter transmission operating
temperatures may be to let the transmission cool down.
If the transmission is operated at higher temperatures
on a frequent basis, see Scheduled Maintenance
on page 6-4 for the proper transmission maintenance
intervals.
TRANS HOT IDLE ENGINE
If the transmission fluid gets hot, this message will
appear on the DIC along with a continuous chime.
Driving with the transmission fluid temperature high can
cause damage to the vehicle. Stop the vehicle and
let it idle to allow the transmission to cool. This message
will clear and the chime will stop when the fluid
temperature reaches a safe level.
DRIVER DOOR AJAR
If the driver’s door is not fully closed and the vehicle is
in a drive gear, this message will appear on the
display and you will hear a chime. Stop and turn off the
vehicle, check the door for obstacles, and close the
door again. Check to see if the message still appears on
the DIC. Pressing the select button will clear it from
the DIC display.
